Then how can I get a RevCon error at a junction when the junction is at the 'entrance' end of a one-way street?

Depending on how Tim implemented it he may be showing SelfCon on a one-way segment as RevCon.

'qw'ing fixes RevCon because there's a legal turns vs road direction check on 'w'. 'qw'ing doesn't fix SelfCon because the 'q' function currently only looks at connections to other segments and ignores connections back to the same segment.

In other words you are driving up a segment and Waze tells you to come straight back down the segment at the next junction. I presume that the segment is "connected to itself" and will therefore route back at the end.

Reverse connectivity (purple highlight) I have only seen with one-way segments, where another segment joining the one-way segment at it's "outlet" shows a purple highlight on the one-way segment. I presume this means that, even though it's one way in one direction, Waze sees a valid routing going the other way.

Mind you it is nearly 3am here and I'm watching Sunday Night Football and doing some work stuff and I really should be sleeping! I'm sure someone who knows what they're talking about will come along and correct me.

You've got it all right. SelfCon is effectively allowing routing to perform a u-turn, there's a connection (turn) from and to the same segment. RevCon is a connection into the wrong way of a one-way street, these were created all the time back when WME was called Papyrus, and can still be created by starting with a two-way segment and allowing turns into it, then changing it to one-way.

Something that would be nice, would be for us to be able to select the color of the highlights. i.e. some of the colors that are highlighted I can't see very well due to being color blind to certain colors. I manually hack the code, but I have to do that whenever the script is updated.

It used to be only cities that appeared on streets, but I changed it to show all cities that Waze thinks are in the area. If there has been some renaming, then the old cities will stick around for a while. This is why I added the "= 0" counter to the side, so at least you can be sure that there are no segments in view.
